【摘要】 本文利用Ansys软件建立平面对称与不对称两种异形柱框架结构模型,对两种模型分别输入单向地震波、双向地震波和双向及扭转地震波,进行层间位移角分析。分析结果表明:在两种框架中,多维地震波作用下柱的转角位移比单向地震波要大,尤其是角柱,所以抗震设计时应考虑地震的多维作用并注意角柱的加强。更多还原

【Abstract】 The plane symmetrical and unsymmetrical specially-shaped column frame models were established using the ANSYS software,then the analysis on values of story drift was carried on when the one-way seismic waves,bidirectional seismic waves and the rotational and the translational components were input to the above models separately.The result indicated that Values of Story Drift of columns under multi-dimensional seismic waves are larger than one-way seismic waves,especially for the corner columns.Therefore,the multidimensional effects of the earthquake should be taken into account and the corner columns should be strengthened when designing.更多还原
